c27b3758fa nir/opcodes: Add new 'umul_low' and 'imadsh_mix16' opcodes
'umul_low' is the low 32-bits of unsigned integer multiply. It maps
directly to ir3's MULL_U.

'imadsh_mix16' is multiply add with shift and mix, an ir3 specific
instruction that maps directly to ir3's IMADSH_M16.

Both are necessary for the lowering of integer multiplication on
Freedreno, which will be introduced later in this series.

4e3297f7d4 egl/x11: calloc dri2_surf so it's properly zeroed
Commit 2282ec0a refactored drawable creation across various platforms
into a new dri2_create_drawable helper function.

The GBM code in platform_drm.c code passed in dri2_surf->gbm_surf as the
loaderPrivate, while most other backends passed in dri2_surf directly.

To try and handle this, the patch checked if dri2_surf->gbm_surf was
non-NULL, and if so, presumed that the caller is the DRM platform and
we should use the dri2_surf->gbm_surf pointer.

This worked for most platforms, which calloc their dri2_surf structure,
zeroing the data.  Unfortunately, platform_x11.c used malloc, leaving
most of the dri2_surf as garbage.  In particular, dri2_surf->gbm_surf
was often non-NULL, causing dri2_create_drawable to try and use it,
passing a garbage pointer to the createNewDrawable hook, usually leading
to a SIGBUS or SIGSEGV when trying to dereference that bad pointer.

Since most callers calloc the data, make platform_x11.c follow suit.

Fixes crashes with i915_dri.so when running dEQP-GLES2.

110f139f98 anv: allow NV12 <--> AHARDWAREBUFFER_FORMAT_Y8Cb8Cr8_420 inter-op
AHARDWAREBUFFER_FORMAT_Y8Cb8Cr8_420 is an implementation defined
flexible YUV format.  Most of the times, it's NV12 or YV12.
On Intel, NV12 is preferred since it can be used by the display
engine.  

This API adds a dependency between gralloc and buffer consumers,
unfortunately.  Right now, the code seems to work for i915 gralloc,
but not cros_gralloc.  Add a preprocessor flag to fix this.

1d55b0da59 radeonsi: Don't force dcc disable for loads
When e9d935ed0e added force_dcc_off(), we forced it off for any
preloaded image descriptor which had stores associated with them, since
the same preloaded descriptors were used for loads and stores. However,
when the preloading was removed in 16be87c904, the existing logic was
kept despite it not being necessary anymore. The comment above
force_dcc_off() only mentions stores, so only force DCC off for stores.

72fc886826 winsys/svga/drm: Fix 32-bit RPCI send message
Depending on whether compiled with frame-pointer or not, the temporary
memory location used for the bp parameter in these macros are referenced
relative to the stack pointer or the frame pointer.
Hence we can never reference that parameter when we've modified either
the stack pointer or the frame pointer, because then the compiler would
generate an incorrect stack reference.

Fix this by pushing the temporary memory parameter on a known location on
the stack before modifying the stack- and frame pointers.

Also in case of failuire RPCI channel is not closed which lead to vmx
running out of channels.

0ba9497e66 intel/fs: Improve discard_if code generation
Previously we would blindly emit an sequence like:

        mov(1)          f0.1<1>UW       g1.14<0,1,0>UW
        ...
        cmp.l.f0(16)    g7<1>F          g5<8,8,1>F      0x41700000F  /* 15F */
(+f0.1) cmp.z.f0.1(16)  null<1>D        g7<8,8,1>D      0D

The first move sets the flags based on the initial execution mask.
Later discard sequences contain a predicated compare that can only
remove more SIMD channels.  Often times the only user of the result from
the first compare is the second compare.  Instead, generate a sequence
like

        mov(1)          f0.1<1>UW       g1.14<0,1,0>UW
        ...
        cmp.l.f0(16)    g7<1>F          g5<8,8,1>F      0x41700000F  /* 15F */
(+f0.1) cmp.ge.f0.1(8)  null<1>F        g5<8,8,1>F      0x41700000F  /* 15F */

If the results stored in g7 and f0.0 are not used, the comparison will
be eliminated.  This removes an instruction and potentially reduces
register pressure.

code).  Suggested by Matt.

a288708506 intel/fs: Add need_dest parameter to fs_visitor::nir_emit_alu
This is the same as the need_dest parameter to
prepare_alu_destination_and_sources.  This allows us to not change the
register that is expected to hold an result if an instruction is
re-emitted.  This is particularly a problem if the re-emitted
instruction is a partial write.  A later patch will use this feature.

No shader-db changes on any Intel platform.

v2: Don't do the Boolean resolve when there is no destination.  If the
ALU instruction didn't write a register, there's nothing to resolve.
This replaces an earlier patch "intel/fs: Allocate dummy destination
register when need_dest is false".

8030cb75c1 intel/fs: Fix flag_subreg handling in cmod propagation
There were two errors.  First, the pass could propagate conditional
modifiers from an instruction that writes on flag register to an
instruction that writes a different flag register.  For example,

    cmp.nz.f0.0(16) null:F, vgrf6:F, vgrf5:F
    cmp.nz.f0.1(16) null:F, vgrf6:F, vgrf5:F

could be come

    cmp.nz.f0.0(16) null:F, vgrf6:F, vgrf5:F

Second, if an instruction writes f0.1 has it's condition propagated, the
modified instruction will incorrectly write flag f0.0.  For example,

    linterp(16) vgrf6:F, g2:F, attr0:F
    cmp.z.f0.1(16) null:F, vgrf6:F, vgrf5:F
    (-f0.1) discard_jump(16) (null):UD

could become

    linterp.z.f0.0(16) vgrf6:F, g2:F, attr0:F
    (-f0.1) discard_jump(16) (null):UD

None of these cases will occur currently.  The only time we use f0.1 is
for generating discard intrinsics.  In all those cases, we generate a
squence like:

    cmp.nz.f0.0(16) vgrf7:F, vgrf6:F, vgrf5:F
    (+f0.1) cmp.z(16) null:D, vgrf7:D, 0d
    (-f0.1) discard_jump(16) (null):UD

Due to the mixed types and incompatible conditions, this sequence would
never see any cmod propagation.  The next patch will change this.

No shader-db changes on any Intel platform.

v2: Fix typo in comment in test case subtract_delete_compare_other_flag.

f06c86358c intel/blorp: Handle SINT/UINT clamping on blits.
This patch makes blorp_blit handle SINT<->UINT blit value clamping.
After reading the source's integer data (which is expanded to 32-bit),
we either IMAX with 0 (for SINT -> UINT, to clamp negative numbers) or
UMIN with (1 << 31) - 1 (for UINT -> SINT, to clamp positive numbers
outside of the representable range).

Such blits are not allowed by the OpenGL or Vulkan APIs directly:

   The Vulkan 1.1 spec for vkCmdBlitImage says:

   "Integer formats can only be converted to other integer formats with
    the same signedness."

   The GL 4.5 spec for glBlitFramebuffer says:

   "An INVALID_OPERATION error is generated if format conversions are
    not supported, which occurs under any of the following conditions:
    [...]
    * The read buffer contains unsigned integer values and any draw
      buffer does not contain unsigned integer values.
    * The read buffer contains signed integer values and any draw buffer
      does not contain signed integer values."

However, they are useful for other operations, such as texture upload
and download, which typically are implemented via blorp_blit().  i965
has code to fall back in this case (which the next commit will delete),
and Gallium expects blit() to handle this case for texture upload.

Fixes the following tests on iris:
- GTF-GL46.gtf32.GL3Tests.packed_pixels.packed_pixels
- GTF-GL46.gtf32.GL3Tests.packed_pixels.packed_pixels_pbo

4f3c82c72c st/nir: Don't use GLSL IR's MOD_TO_FLOOR lowering when using NIR.
Both GLSL IR and NIR perform the same mod -> floor lowering for 32-bit
types.  But nir_lower_double_ops is slightly more defensive against
lowered drcp precision loss, and handles mod(x, x) = 0 directly.  This
works well...assuming nir_lower_double_ops actually gets an fmod op to
lower in the first place.

The previous patches enabled NIR-based lowering for the remaining
drivers, so we can stop using the GLSL IR lowering when using NIR.

f4d4c42608 radeonsi: Enable NIR's lower_fmod option.
Currently, st/mesa is always calling the GLSL IR lower_instructions()
pass with MOD_TO_FLOOR set, so mod operations will be lowered before
ever reaching NIR.  This enables the same lowering at the NIR level,
which will let me shut off the GLSL IR path for NIR-based drivers.

The AMD NIR backend also has code to handle fmod, so we could
potentially skip this and still be fine.  I don't have an opinion
on that.

c7d1b52a2c nir: Combine lower_fmod16/32 back into a single lower_fmod.
We originally had a single lower_fmod option.  In commit 2ab2d2e5, Sam
split 32 and 64-bit lowering into separate flags, with the rationale
that some drivers might want different options there.  This left 16-bit
unhandled, so Iago added a lower_fmod16 option in commit ca31df6f.

Now that lower_fmod64 is gone (in favor of nir_lower_doubles and
nir_lower_dmod), we re-combine lower_fmod16 and lower_fmod32 into a
single lower_fmod flag again.  I'm not aware of any hardware which
need lowering for one bitsize and not the other.
